摘 要：The goal of the Sustainable Painting Operations for the Total Army (SPOTA) program is to significantly reduce the amount of hazardous air pollutant (HAP) emissions produced in coating operations, including adhesives application and removal. Adhesives and sealants account for approximately 5% of U.S. Army-wide HAP emissions from surface coating operations. Materials conforming to Federal specification MMM-A-1617 have been recognized as one of the largest contributors. Laboratory test results previously conducted identified 3M-847 as a suitable HAP-free replacement adhesive that conforms to MMM-A-1617. This report focuses on the field trial conducted at Anniston Army Depot, AL, on a M109A6 Paladin heavy brigade combat vehicle. In particular, the hydraulic compartment door seal was bonded with HAP-free 3M-847 adhesive in place of the baseline (Clifton FA-1051) with successful results. The technicians found that processing the alternative adhesive was similar to that of the baseline, and after six months, the adhesive did not have any signs of blistering, delamination (either cohesively or adhesively), substrate failure, or deterioration of any kind. Overall, the HAP-free 3M-847 adhesive was qualified for use on MMM-A-1617 Army platforms.
